The USC student who was found dead in his bedroom is being mourned by fellow students as the coroner awaits to perform an autopsy on the body. The Los Angeles Police Department is investigating a possible cause of death as "acute alcohol toxicity," but only an autopsy will reveal how the sophomore died.

A University of Southern California student who was found dead by his roommates this weekend may have died from alcohol poisoning just as school officials cracked down on student partying, officials said Monday.

Thu Yain Kyaw, a sophomore from Singapore whose friends called him "Roy," had not been seen for a few days after a party at his home in the 1300 block of W. 29th Street, just blocks from USC's South Los Angeles campus, according to the Los Angeles Police Department.

No one checked Kyaw’s room until Sunday, when his roommates found their friend dead.

The Los Angeles County Coroner has not yet performed an autopsy but the LAPD is investigating Kyaw's preliminary cause of death as "acute alcohol toxicity."

"It is with enormous sadness that I write to inform you of the sudden passing of a member of our Marshall community and the Trojan Family, Thu Yain 'Roy' Kyaw," USC Dean James G. Ellis said in a statement.

A letter from the assistant dean for Student Affairs called Oct. 12 "the worst weekend of the semester" after seven people were taken to the hospital for drinking too much alcohol. One girl suffered a head injury after falling from a table at a Sigma Alpha Epsilon party.

"I think people are excited to be back in school, and that’s why it’s been out of hand," USC student Nickey Feeney said.

USC Student President Christian Kurth said the improvements were needed. Student groups, though, are pushing back against a new policy that would force students to front the money for any extra security at student-organized events.

"Do we scale back on our events to pay for security?" Kurth said. "What are we going to do? That’s the challenge we’re working with."

Student groups were scheduled to meet with administrators Tuesday to talk about alcohol on campus.

A previous version of this article stated that the coroner said Kyaw's cause of death was acute alcohol toxicity, but only the LAPD gave that as a preliminary cause of death. The coroner has not yet performed an autopsy.
